From TrainzOnline
Notch '<value>' in the '<container>' container is beyond valid range and will not be used.
A notch number in an engine asset power or brake graph is higher than the number of throttle notches the engine actually has, so the data for that notch will never be used.
Remove the out-of-range notch data, or correct the notch numbering so it falls within the engine's throttle notch count. If your engine genuinely has more than 8 throttle notches and you want data for each, set the motor's 'throttle-notches' and enable the extended-notch-range option for that container (requires trainz-build 5.8 and later); otherwise the graph assumes 8 notches.
